Horizontal bracing

When supporting low-fire-potential equipment Support structure should be fireproofed from its base up to the platform or horizontal bracing plane nearest to an elevation of 40 ft (12 m), but should not terminate below 30 ft (9 m) (see Figure 8-8). 

Figure 9.7. Desensitization of the nicotinic acetylcholine receptor. a Experimental setup. Presynaptic action potentials were triggered, and postsynaptic ones were detected using two separate sets of electrodes, b Perfusion of the synapse with extraneous acetylcholine (during the time interval indicated by the horizontal brace) brings about a sudden depolarization. Continuous presence of acetylcholine rapidly suppresses the response to presynaptic action potentials also, the membrane potential returns to levels near the resting potential. Discontinuation of the acetylcholine results in restoration of response to presynaptic stimuli.

The main vertical members are continuous they are connected by means of glued nodal pieces to diagonal and horizontal bracing elements. 

The horizontal bracing bars were subjected to a rather high bending moment. Their amplification beyond the ultimate buckling state explains the bursting out of the nodes. 

The SFP itself musf be capable of holding the significant weight associated with the racks, spent fuel, and wafer under normal and accident conditions. The key SFP structural members include four reinforced concrete walls and a base slab that are lined with a stainless steel liner. The pool walls are supported by reinforced concrete columns and a mass foim-dation. The SFP may also be supported by a system of caissons that extend below the pool slab through the supporting soil and into the underlying bedrock. Floor slabs adjacent to the SFP walls provide horizontal bracing. 

Achieving both convex and concave curves between the vertical drop-downs and The wavy nature of the fascia meaning horizontal bracing will be seen at the points where the curve rises above the horizontal supports within a span between droppers. 

The roof steel structure (Fig. 14) consists of six parallel main arches having a span of 60 m and spaced at a distance of 10.5 m that are interconnected by means of purlins and horizontal bracings. Each main arch is pinned on the ground on one edge, while the other edge is supported by a V-shaped column. The arches are suspended by prestressed cables from a 25 m tall pylon, which has a slight inclination with respect to the vertical plane. The stability in and out of plane of the pylons is ensured by two back-stayed prestressed cables. 

Applications for structural steel in blast resistant design include beams and columns for the support of vertical loads, braced and rigid frames for the support of vertical and horizontal loads, and specialized elements such as doors, window frames, decking, and protection for duct openings. For lower blast loads, steel siding can be used. 

A type of matrix that is of considerable importance is the one-column matrix. To have the convenience of writing such a matrix all on one line, it is sometimes written out horizontally but enclosed in braces,, so as to distinguish it from a one-row matrix, which is normally written on one line in square brackets. The chief significance of the column matrix, at least for our purposes, is that it affords a way of representing a vector. Indeed it is sometimes actually called a vector. 

The upper surface of the baseplate s center is a recessed socket with a latching collar to accept and retain the round base of the barrel, which is free to pivot in all directions. When in use, the barrel may be adjusted vertically from 40° to 85°.Transverse or horizontal movement is 5" total, or 2.5" left or right of center, as measured at the transverse mechanism. The underside of the baseplate is fitted with four triangular feet that dig firmly into the ground to stabilize the mortar under fire.The front edge carries an additional row of four smaller feet that aid in stability.The four main feet,as well as the central socket area, are tied together and reinforced with several gussets and braces. 

Even though the experimental results are still limited, it appears that the predicted occurrence conditions provide the general trend compatible with the experimental results. Thus, it may be possible to examine the fracture process to be expected for hydraulic stimulation in supercritical rock masses on the basis of the fracture mechanism map given in Fig. 4. The ratio of the minimum horizontal tectonic stress to the vertical tectonic stress usually falls in the range of 0.5-1.0 for brittle rock masses (Brace Kohlstedt, 1980.). The actual difference of the tectonic stresses may be significantly smaller in supercritical rock masses due to the high temperature creep deformation (Fournier, 1999 Muraoka et al., 20()0). If we limit... 

Leg supports may be braced or unbraced. Braced legs are those which are reinforced with either cross-bracing or swaybracing. Sway braces are the diagonal members which transfer the horizontal loads, but unlike cross braces, they operate in tension only. The diagonal members in a sway-braced system are called tie rods, which transfer the load to each adjacent panel. Turnbucldes may be used for adjustments of the tie rods.

This procedure is used for calculating the distribution of vertical and horizontal forces due to wind or seismic loadings for vessels, spheres, elevated tanks, and bins supported on cross-braced legs or columns. 

The horizontal load on any one leg is dependent on the direction of the reactions of the leg bracing. The horizontal force, V, is transmitted to the legs through the bracing. Thus, the general equation ... 

The primary shield is demolished by remote operation from the enclosure. The planning is to install a platform below the primary shield in the reactor cavity on which parts of the primary shield can be deposited. The parts of the primary shield are then disassembled by means of a saw which can be carried by the crane it is applied to the component, braced, and thus allows horizontal and vertical cutting. 

Neater Arm Support (Neater Solutions Ltd., Buxton, UK) is a commercially available motorized arm support device that enables people with muscle weakness to use their arms [71]. It allows free motion within a horizontal plane via a serial link mechanism having three free rotational joints. One additional inclined rotational joint connecting the forearm brace and link mechanism allows automatic lowering of the elbow upon raising the hand to the level of the mouth. Only the vertical motion is motorized and the user manually controls this motion using buttons to raise or lower the arm. 

Stmctural elements which are assumed to transfer stabilising forces from the elements of a structure to be braced to the bracing elements should be designed to carry an additional horizontal force Hfd such that ...
